Get out of the path of the landslide quickly.
Evacuate if your home or the building you are in is in danger — take your grab bag and pets with you if you can do so quickly.
Warn neighbours and help others if you can.
Contact emergency services and your local council.
Stay alert for future landslides.
Stay away from affected sites until they have been properly inspected and authorities give the all clear.
Report broken utility lines to appropriate authorities.
Re-plant damaged ground as soon as possible because erosion caused by the loss of ground cover can lead to flash flooding.
A landslide is the movement of rock, soil and vegetation down a slope. Landslides can range in size from a single boulder in a rock fall to a very large avalanche of debris with huge quantities of rock and soil that spreads across many kilometres. Landslides are a serious geological hazard in many parts of New Zealand.
Heavy rainfall or earthquakes can cause a landslide. Human activities, such as removal of trees and vegetation, steep roadside cuttings or leaking water pipes can also cause landslides. Be aware of the warning signs.
New Zealand’s mountainous land, loose volcanic soil and frequent earthquake activity make landslides common in many parts of the country.
It’s important to recognise the warning signs and act quickly.
